It depends on the cross section which may be circular, elliptical, square, rectangular or of a more complex shape.
If the bar is circular then it is: pi*radius square
3.1416"Answer:3.1416 square inches.
The area between bar lines
The dot of an 'i' is called a tittle and the cross of a 't' is called a T-bar.
The extra line found on most Orthodox (specifically Russian) crosses is the bar that held Christ's feet. During crucifixion, there was a bar for the feet to rest before they were nailed to the wood.
If the bar is circular then it is: pi*radius square
A Y12 bar typically has a cross-sectional area of 113 square millimeters.
volume of steel multiplied by7850= wt of steel in kgs. Please note that wt of 1 Cum steel is 7850 kg Volume of steel bar can be calculated = cross-sectional area of bar X length cross-sectional area of Bar= pie x d X d/4 (where d is diameter of bar)
3.1416"Answer:3.1416 square inches.
The formula to calculate the area of a steel bar is A = πr^2, where A represents the area and r is the radius of the steel bar. This formula assumes that the steel bar is circular in shape. If the steel bar is a different shape, such as rectangular or square, the formula to calculate the area would be different based on the dimensions of the bar.
Most rebar (steel reinforcement bar) is approximately round. Measure the diameter of the bar, that is, the thickness of the bar. Divide the measurement by 2 to get the radius. Use the formula pi x r2 (3.14 x radius x radius) to get the cross sectional area. The formula works for all measurement units whether they are inches, millimeters, centimeters or others. An alternative is to use (pi x d^2)/4. (3.14x diameter x diameter divided by 4) You do not then need to divide the original diameter.
Calculate cross sectional area of 10mm bar amd 8mm bar, then divide them and you will get the no. of bars. For Eg. - Area of 10mm bar = 78.53 sq.mm Area of 8mm bar = 50.26 sq.mm No. of 8mm bars in replacement for 10mm bar = 1.562 bars [ theoritical] In practical u'll provide 2-8mm bars.
as every size bar differ in diameter and possibly type, the reinforcement steel is measured in kilograms per meter, say 8.5kg/m. the steel weight is actually calculated, as a % of the cross-sectional area. different applications have different minimum % steel required, roughly work on 1%. the sum of the bars cross sectional area at each support and spans are seperately calculated and compared to the cross sectional area of the concrete, hence expressed as a %.
The Ixx and Sxx values of a steel bar refer to its moment of inertia (Ixx) and section modulus (Sxx) about its x-axis, which is typically the axis about which bending occurs. The moment of inertia (Ixx) is a measure of the distribution of the cross-sectional area relative to the axis, affecting how the bar resists bending. The section modulus (Sxx) is derived from the moment of inertia and is used to determine the strength of the section under bending loads. These values depend on the specific cross-sectional shape and dimensions of the steel bar.
To determine the appropriate cross-sectional area for a copper bus bar carrying 5000 A at 56 V DC, one must consider the current density. A typical safe current density for copper is around 1.5 A/mm². Therefore, the required cross-sectional area would be approximately 5000 A / 1.5 A/mm² = 3333.33 mm². However, to account for factors like heat dissipation and potential overloading, it’s advisable to select a larger cross-section, often around 25-30% more, leading to a final area of about 4000 mm² or more.
Rod is circular in shape. If u look it from where it starts, i.e. its cross sectional view it will be circular. It may or may not be hollow. Bar's cross sectional view will be a quadrilateral. Shivangini
Assuming that the bar is made of steel & of circular cross-section & loaded in simple tension, Stress= Load applied/area of the bar. In SI units, area = Pi x (diameter)2/4 "square metre" Apply the load in "Newtons". then calculate the stress developed in N/m2
